INDUSTRIAL APPLICATION FIELD The present invention relates to oral compositions, such as toothpastes and profilakis pastes, which have moderate abrasiveness and excellent cleaning effects on teeth, and are highly effective in imparting gloss to tooth surfaces. Prior art and its problems In general, oral compositions such as toothpastes and profilakis pastes have a high ability to efficiently remove stains, plaque, food particles, and other substances that have adhered to or deposited on teeth by physical action. It has excellent polishing and polishing properties that do not damage the tooth surface, and it also gives excellent gloss to the tooth surface, smoothing the tooth surface and preventing the deposition of plaque and tartar. What is possible is desired. In this case, the efficiency of physical removal of stains, plaque, food particles, etc. can be increased by increasing the abrasive power of the abrasive. In particular, in the past, increasing the abrasive power improved the tooth surface cleaning effect. However, increasing the polishing power and
Preventing damage to the tooth surface and adding gloss to the tooth surface are generally contradictory, and the higher the polishing power, the more easily the tooth surface will be scraped and damaged, and may even cause wedge-shaped defects. Also, the polishing power is too high,
The more the tooth surface is damaged, the more it reduces the gloss of the tooth surface.
In particular, since the main purpose of profilakis paste is to remove strongly deposited stains, plaque, tartar, etc., care is taken to ensure that the polishing force is sufficiently high, and consideration is given to damage to the tooth surface. Currently, very little is being done. When brushing teeth, care is taken not to damage the tooth surface, but there are very few things that can improve the gloss of the tooth surface. For this reason, there has been a demand for an abrasive that does not damage tooth surfaces, gives gloss to tooth surfaces, has appropriate abrasive power, and has excellent cleaning effects. It is known that α-alumina and titanium dioxide have the effect of imparting gloss to the tooth surface, but when used in combination with a highly abrasive abrasive, the abrasive with a high abrasive power may cause the tooth surface to become glossy. The surface may be damaged and its gloss imparting effect may not be fully exhibited, and if it is used in combination with an abrasive with low abrasive power, cleaning performance may be problematic. Features of the Invention The present inventors have conducted extensive research into oral compositions that have a high glossing effect on tooth surfaces, high cleaning power, and moderate abrasive power. Modified aluminum hydroxide obtained by treating with salt, especially modified aluminum hydroxide obtained by treating aluminum hydroxide produced using a rotary impact mill with an acid or a salt thereof. , gelatinization rate 15-85%
When used in combination with titanium dioxide containing 70% by weight or more of alumina anhydride and/or rutile-type crystal structure, it has moderate abrasiveness and excellent cleaning effect on teeth, and has a good cleaning effect on tooth surfaces. It has been found that an oral composition with excellent gloss imparting effect can be obtained. That is, the present inventors have found that the above-mentioned modified aluminum hydroxide, especially the modified aluminum hydroxide produced by a rotary impact crusher, has excellent low polishing and high cleaning properties, and that this modified aluminum hydroxide and gelatinized rate 15~85
% alumina anhydride and/or titanium dioxide containing 70% by weight or more of rutile type crystal structure, the synergistic action of these results in low abrasiveness, high cleaning effect, and high The present invention was based on the discovery that an oral composition with extremely excellent gloss-imparting properties can be obtained. The present invention will be explained in more detail below. Composition of the Invention The oral composition according to the present invention comprises modified aluminum hydroxide obtained by treating aluminum hydroxide with an acid or a salt thereof, anhydrous alumina with a gelatinization rate of 15 to 85%, and/or It is made by blending titanium dioxide, which contains 70% by weight or more of rutile-type crystal structure. The modified aluminum hydroxide used in the present invention is obtained by treating aluminum hydroxide with an acid or its salt. In this case, there is no particular restriction on the aluminum hydroxide used for modification, and a normal method can be used. A commercially available product can be used. Note that the average particle size of the aluminum hydroxide used is preferably 1 to 30 microns, particularly 3 to 20 microns, from the viewpoint of processability. In this case, it is preferable to use aluminum hydroxide that has been pulverized into the desired shape and particle size using a ball mill, jet mill, rotary impact pulverizer, etc., and the abrasive power of the resulting modified aluminum hydroxide can be varied in various ways. can be adjusted to In this case, in the present invention, it is particularly preferable to use modified aluminum hydroxide obtained by treating aluminum hydroxide pulverized using a rotary impact pulverizer with an acid or its salt; Compared to modified aluminum hydroxide obtained by treating aluminum hydroxide ground using a ball mill or jet mill with an acid or its salt, the average particle size is larger when the polishing power is the same, and therefore Since the cleaning power is high when the polishing power is about the same, by using the modified aluminum hydroxide produced by this rotary impact crusher, it is possible to obtain an oral cavity composition that is particularly excellent in low polishing and high cleaning performance. Moreover, as the acid or salt used for modifying the aluminum hydroxide, inorganic acids, organic acids, and salts thereof can be used. Examples of inorganic acids and their salts include phosphoric acid, sulfuric acid, hydrochloric acid, and their salts, and examples of organic acids and their salts include acetic acid, oxalic acid, tartaric acid, succinic acid, and their salts. Among these, phosphoric acid and its salts are preferably used, and such modified aluminum hydroxide has a 10% (wt%) water slurry with a pH of usually about 5 to 8, and is not modified. The pH of 10% water slurry of aluminum hydroxide is usually 9.
Since the pH is considerably lower than that before and after, the composition is not prepared to have a high pH, and therefore the fragrance ingredients,
In particular, it is possible to suppress the decomposition and deterioration of ester-based perfume components, and therefore it is possible to freely create perfumes using various perfume components. Here, phosphoric acid and its salts include orthophosphoric acid (H 3 PO 4 ), pyrophosphoric acid (H 4 P 2 O 7 ), metaphosphoric acid (HPO 4 ), triphosphoric acid (H 5 P 3 O 10 ), Tetraphosphoric acid (H 6 P 4 O 13 ). , condensed phosphoric acids such as polymetaphosphoric acid (HPO 3 ) n), and alkali metal salts thereof, and these can be used alone or in combination of two or more. In addition, the alkali metal salts include hydrogen phosphate-alkali metal salt (MH 2 PO 4 ), di-alkali metal hydrogen phosphate (M 2 HPO 4 ), and tri-alkali metal phosphate (M 3 PO 4 ).
Examples include. The method of treating aluminum hydroxide with an acid or a salt thereof is not particularly limited, but for example, a method of suspending aluminum hydroxide in an aqueous solution of an acid or a salt thereof and performing a neutralization treatment to carry out modification is possible. It can be suitably adopted. In this case, the aluminum hydroxide is preferably a 10 to 90% by weight slurry of an aqueous solution of an acid or its salt, particularly a 30 to 70% by weight slurry, and the concentration of the acid varies depending on the concentration of the aluminum hydroxide added. However, 0.05 mol/l ~ 5
Preferably it is mol/l. Also, the reaction is 10
It is preferable to carry out the reaction at -50°C, particularly 20-30°C, for 2-50 hours, especially 2-30 hours, and it is preferable to carry out stirring during the reaction. After the above operation is completed, the aluminum hydroxide removed from the slurry by filtration is washed with water or the like and dried to obtain modified aluminum hydroxide. In addition, in the above-mentioned reforming operation, it is also possible to perform the reforming operation once or repeatedly using one or more of the acids or salts at the same time,
The modification operation can also be repeated using two or more different acids or salts. For example, aluminum hydroxide is first treated with sulfuric acid, hydrochloric acid, etc.
It can then be treated with phosphoric acid, etc. Among the modified aluminum hydroxides mentioned above,
Particularly preferred are those obtained by treatment with phosphoric acid or its salts, especially orthophosphoric acid or its alkali metal salts. Products modified with this phosphoric acid or its salt have an aluminum phosphate-containing layer formed on the particle surface, but when using this type of modified aluminum hydroxide, the aluminum phosphate-containing layer on the surface A layer in which the entire layer is made of aluminum phosphate may be used, or a layer in which aluminum hydroxide and aluminum phosphate coexist may be used, but ESCA

It is preferable to use one that indicates the presence of %. The above-mentioned modified aluminum hydroxide preferably has an aluminum phosphate-containing layer thickness of 10 to 1000 Å, and
Preferably, P 2 O 5 min is 0.01-0.5%. In the present invention, the above-mentioned modified aluminum hydroxide is blended into oral compositions such as toothpaste. In this case, the modified aluminum hydroxide is
This is slurry suspended in water at a ratio of 10% by weight.
It is preferable to use one having a pH of 4 to 8 and a copper plate polishing value of 1 to 10 mg. In addition, the copper plate polishing value is calculated by preparing a regular toothpaste containing 50% modified aluminum hydroxide, taking 50g of it, and adding 40g of it.
This is the abrasiveness when dispersed in 60% glycerin and subjected to 20,000 strokes using an inclined abrasive tester (pepsodent type). ), see page 184]. In addition, when using modified aluminum hydroxide as an abrasive, it is preferable that the average particle size is 1 to 30μ, particularly 7 to 25μ;
If it is larger than 30μ, a rough feeling may occur, and if it is smaller than 1μ, the polishing properties may be poor.
However, when used as a polishing agent, finer particle sizes can also be used. Furthermore, in the present invention, α-alumina and/or
Alternatively, titanium dioxide is blended into an oral composition. In this case, the α-alumina used in the present invention is alumina anhydride (Al 2 O 3 ) with a α-ization rate of 15 to 85%, preferably 20 to 80%, and this type of alumina anhydride is used. By doing so, excellent gloss can be imparted to the tooth surface. In addition,
Alumina anhydride with a gelatinization rate of 15 to 85% is α-
Al 2 O 3 , γ-Al 2 O 3 , amorphous Al 2 O 3 , etc. are combined in appropriate proportions, and the peak of α-Al 2 O 3 of the alumina anhydride is conversion rate 100
When compared with the peak of alumina anhydride (α-Al 2 O 3 ) with a gelatinization rate of 100%, the peak is between 15 and 85% of that of alumina anhydride (α-Al 2 O 3 ) with a gelatinization rate of 100%. do. Specifically, α− with a α conversion rate of 100%
The diffraction X-ray intensity ratio between the (012) plane and the (116) plane with Al 2 O 3 is determined, and the average value is 15 to 85%. Here, the alumina anhydride having a gelatinization rate of 15 to 85% may be used alone or in combination of two or more. Also, the gelatinization rate is 15-85%
The alumina anhydride may be used in combination with other alumina anhydrides or hydrates. Note that the alumina anhydride with a pregelatinization rate of 15 to 85% can be produced by the Bayer method, and can have a desired pregelatinization rate by appropriately controlling the firing temperature in the Bayer method manufacturing process. Alumina anhydride can be obtained. Further, the average particle size of α-alumina used in the present invention is not necessarily limited, but is preferably 10μ or less,
The particle size is preferably 5 μm or less, particularly 0.1 to 3 μm; if the particle size is too large, the gloss imparting effect may deteriorate. In particular, it is most preferable to have an average particle size of 5 μm or less in terms of gloss imparting and polishing power. In addition, as titanium dioxide used in the present invention,
Titanium dioxide containing 70% or more of rutile-type crystal structure is used, and by using this type of titanium dioxide, excellent gloss can be imparted to tooth surfaces. The titanium dioxide used in the present invention must not be surface-treated and its purity must be
It is preferable that it is 98.5% or more from the viewpoint of gloss improvement effect. Furthermore, the average particle size of titanium dioxide used in the present invention is not necessarily limited, but is 0.1 to 0.8μ, particularly 0.1 to 0.8μ.
The particle size is preferably 0.5 μm, and if the particle size is too large, the gloss imparting effect may deteriorate. In the present invention, there is no limit to the amount of the modified aluminum hydroxide, α-alumina, and titanium dioxide;

In this case, 0.1 to 100 parts by weight of titanium dioxide per 100 parts by weight of modified aluminum hydroxide, especially 1
It is preferred to use ~70 parts by weight. The total amount of modified aluminum hydroxide, α-alumina and/or titanium dioxide is usually 5% of the total composition.
~95%, especially in the case of toothpaste, preferably 5-50%. In this case, in the present invention, the abrasive and brightener may be composed only of the above-mentioned modified aluminum hydroxide and α-alumina and/or titanium dioxide, but may be used in combination with other abrasives. Here, other abrasives include, for example, calcium hydrogen phosphate dihydrate, calcium hydrogen phosphate anhydrate, calcium carbonate, calcium pyrophosphate,
Examples include insoluble sodium metaphosphate, precipitated silica, aluminosilicate, aluminum oxide, microcrystalline cellulose, resin, tertiary magnesium phosphate, and magnesium carbonate. Further, conventional aluminum hydroxide can also be blended within a range that does not significantly impair the properties of the modified aluminum hydroxide. In addition,
When modified aluminum hydroxide is used in combination with other abrasives, the ratio is not limited, and modified aluminum hydroxide may be used as the main abrasive, or other abrasives may be used as the main abrasive. Although these are determined depending on the purpose of use of the oral composition, the modified aluminum hydroxide of the present invention is mixed in an abrasive with a concentration of 20 to 100%.
